Serial No. 459,332.

This invention relates to ventilators and methods of making the same.

One object of this invention is to provide a device of the character described including an improve-d ventilator which may form a unitary structure with a window sash.

Another object of the invention is the provision of a device of the type mentioned in which a window sash is divided into a plur- 0 ality of sections by cross bars, and the panel of one of the sections is movably mounted in an improved manner to preserve the full light area of the section as well as the conventional appearance of the sash to a relatively close degree.

Another object of the invention is to afford an improved mounting for a sliding panel, wherein the mounting is so constructed as to be readily applicable to practically any existing sash structure without any substantial change in appearance or deforma-tion thereof.

Another obj-ect of the invention is to provide a sliding glass panel ventilator and a locking device having improved coaction therewith and with the window sash.

Another object of the invention is the provision of an improved method of constructing a sliding panel ventilator in a window sash, and particularly where the latter has already been made along conventional lines.

A further object of the invention is the provision of a device of the class alluded to having comparatively few and simple parts, which is inexpensive to manufacture and assemble, rugged, reliable and efficient in use, neat` in appearance, easy and convenient to operate, weatherproof, free from vibration, and which conforms with the best architectural practice.

Other objects and advantages of the invention will become apparent as the specification proceeds.

Vith the aforesaid objects in view, the invention consists in the novel combinationsl and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated on the Yannexed drawing, wherein likeparts are designated by the same reference characters throughout the several views.

y rlhe advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

lt will be obvious to those skilled in the art to which this invention appertains, that the same may be incorporated in several different constructions. rlhe accompanying drawing, therefore, is submitted as showing the preferred exemplication of the inven` tion.

Generally described, this invention provides a ventilator which is arranged as part of a window sash, Reference may be had to sashes of the type which have cross bars that divide them into a plurality of sections. According to the invention, one or more of these sections of aV window sash has a panel which is movable to permit the section to be opened for ventilation. The mounting is so arranged as not to-reduce the light area of the lportions for the sliding panel.

section. While the specific mounting can be made to suit, it is preferably constructed for a sliding movement of the Ventilating panel, although yhinged connections may also be used. To prevent the sliding mounting from obstructing the light line, grooves or tracks may be provided within the bars for the sliding panel. These tracks may be variously constructed directly within the bars, although in order to obtain a high degree of air tig tness, I prefer to use metallic tracks closely engaging the .edges of the panel. The tracks eXtend through a slot in an adjacent bar and alongside of an adjoining section, so that the panel is movable through said slot into open position. The tracks may be of one piece construction and in the shape of a U, .the ends of the U having resilient stop By setting the tracks into recesses or rabbets in the bars of the sash frame, the light line of the sash section is unchanged. A felt or similar strip may be provided in the rabbet in the slotted bar to make a weather tight connection with the panel at this point. To afford tight engagement between the tracks and the sash frame, any suitable fastening means may be used, whether metallic, or of a setting composition material, such as putty. To hold the sliding panel closed, a catch device may be employed which automatically engages when the panel is closed. The panel may be retained in partially open position `by frictional. engagement of the tracks therewith.

Referring in detail to the drawing, 10 denotes a conventional window sash to which the invention may be applied. rl`he window may be of a sliding or hinged type, and can constitute a part of a door construction. In the form shown, the window includes stiles 12 and upper and lower rails 18. Dividing the sash into a plurality of sections 1li are vertical and horizontal cross bars 15.y 1G which intersect eachother. Panels 17 of glass or other suitable material are mounted for the individual sections. To receive the said panels, Vthe sash frame is rabbeted as at 18, and putty or equivalent plastic composition material 19 may be applied at the rabbets. lt will be appreciated that any conventional window structure may be employed, whether made of Vwood or metal, and regardless of the specific details of the structure, since the invention which will now be described may be applied to any paneled type of window, and maybe readily modified to suit various kinds of window constructions. It can also be constructed in windows which have already been manufactured and are in use. Y

Any one of the sections 14, such as a section 2O may be constructed to include the ventilator that embodies this invention. This ventilator may include a slidable glass panel 21 which may be mounted for movement in a horizontal direction. However, the ventilater may be .diiilerently arranged to include a panel 22 shown in Fig. 3 which is movable in a vertical direction. The same construction may be employed for both types of ventilators, except'that the locking devices may be slightly different.I as hereinafter` described.

rlhe sliding panel 21 is mounted for movement along a plane parallel to the fined panels 17 but slightly spaced toward the outside thereof. lllhen the ventilator is to be Opened, the sliding panel is moved into an adjoining section 14.

To guide the sliding panel in its movement and to adord a weathertight engagement substantially free of rattling or vibration, a track 22 may be employed. rlhis may be made of any suitable material, preferably of sheet metal, and .is so shaped as to reliably hold the panel. The track may be slightly resilient in character if desired. It can' be of any suitable shape in cross section, and may include one or more sides 23 which may slightly converge toward each other for snugly gripping` the panel. One simple type of track of the l) section shown,

The track may be made to engage two or more edges of the sliding glass panel, accordina` as may be considered necessary to make the ventilator t ht in the closed position. Thus, the trac,y may be made of U forni., including side portions 24 and an end port-ion 25 interconnecting` the same. This or any other track, with the glass panel 21 therein. is positioned in the rabbet 18 so as to avoid any part of the track from projecting into the light line, and reducing the light rea of the ventilator section 20.

rl`he track may be of suiiicient length to exten d into an adjoining section, the intermediate cross bar 26 being slotted at 27 for the reception of the track. The free end portions 28 of the track extend closely along the fired panel 17 and act as a holding means therefor. the putty line for the panel 17 continuing from said ends. To secure the tracks in place, fastening` means such as screws 29 may be passed into the frame through the portions 30 or other parts of the track. The connection between the tracks and the sash frame is, however, made weathertight by the use of putty 31, or the like, which acts as a continuous seal. lnto the end portions of the tracks may be placedresilient stop elements 32, which may consist of rubber, felt, or the like, and serve to prevent jarring of the panel 21 when the ventilator is opened. A recess 33 or portion of a rabbet 18 receives a strip of flexible or resilient material, such as rubber or felt 34 which is secured therein in any suitable manner, and has sliding contact with the panel 21 to render the ventilator weathei` tight. i

To lock the ventilator in closed position, a locking device is used, which may include ahook element S6 extending into a recess 3T in a cross bar and pivotally mounted therein on a pin or screw 38. Secured to the glass panel 21 is a. knob-like engagementmember 39 fastened thereto by a threaded portion el@ and nut 41. To cause the element 36 to autematically engage the member 39 when the ventilator is closed, the former has a cani shaped portion Zl2 adapted to ride over the member 39 and cause the interlocking of the device.

ln Figs. 9 and 10 is shcwn a locking` device 43 applicable to the vertically sliding panel 22 shown in Fig. 3. rlhis device includes a catch all pivotally mounten on a pin 45 to gravitationally depend and engage a catch 4b. rlhe latter is formed on a plate A7 secured to the panel 22 by screws 48. An integral 'linger piece 4.9 serves for movement ofthe panel 22. When this panel is partially open, the frictional contact therebetween and the track holds the panel against unintended movement.

it will be seen that uniformity in appearance of all sections of the window sash is by this invention retained to a substantial degree. rlhe light areas of the ventilator sections are not reduced or obstructed by the tracks. rfhe inside ornamental character of the window sash is maintained uniform and neat. rlhus the ventilator is relatively inconspicuous, and the conventional nature of the window is retained. In fact, these observations are also true of the outside of the window. Only the locking devices may be noticed, but these are relatively small. lt will be understood that any other types of locking` devices may be used, and that they can be otherwise positioned. Thus this invention can well meet the most stringent architectural requirements,

The method of constructing the ventilator in any existing paneled window sash will now be described. One of the glass panels is removed, and a portion of a cross bar cut away. as at 49. down to the plane of the outside surface of an adjoining fixed panel 17. Also a portion of the putty at the latter is removed. Then the track, with the sliding pan-el therein, is set into the rabbet 18 at the cpening 50 made by removing a panel, and the track is secured in place by screws and putty. The locking device and felt strip 34 are putin place, and finally a bar 51 is mounted to provide the slot 2'?. rEhe shape of the bar 51 may be such as to simulate putty line. Now the device is complete and ready for use.

It will be appreciated that various changes and modifications may be made in the conbeing submitted in an illustrative, not in a limiting sense.
